WebMar 1, 2004 · β 2-Transferrin, the asialo form of transferrin, is produced by neuraminidase activity in the brain and is usually detectable only in CSF, perilymph, and aqueous humor. Thus, like β-trace protein, it is a potentially useful marker to diagnose CSF leakage ( 3 ).

In medicine, the urea-to-creatinine ratio ( UCR [1] ), known in the United States as BUN-to-creatinine ratio, is the ratio of the blood levels of urea (BUN) (mmol/L) and creatinine (Cr) (μmol/L).

WebThe cerebrospinal fluid (CSF) variant of transferrin is identified by its unique electrophoretic migration. If beta-1 and beta-2 transferrin are detected in drainage fluids, the specimen is presumed to be contaminated with CSF. The presence of beta-2 transferrin band is detectable with as little as 2.5% spinal fluid contamination of body fluid. WebFeb 1, 2015 · Cerebrospinal fluid (CSF) leaks may present as rhinorrhea or otorrhea and can lead to life-threatening complications if not detected. The usefulness of the morpholinopropanesulfonic acid (MOPS)–histidine buffer in detecting β 2-transferrin, which is only found in the cerebrospinal fluid, was compared with the standard barbital buffer.
http://www.e-biochem.com/product.php?id=345699 WebTransferrin that migrates in the beta-1 electrophoretic fraction (beta-1 transferrin) is found in most body fluids. Beta-2 transferrin is a CSF-specific variant of transferrin and is used as an endogenous marker of CSF leakage. Beta-2 transferrin is formed by loss of sialic acid due to the presence of neuraminidase in the central nervous system.
WebCSF leakage can be seen on scans but if doubt remains then a useful test is detection of beta-2 transferrin (also known as asialotransferrin or tau protein) β-2-transferrin is a carbohydrate-free (desialated) form of transferrin, almost exclusively found in the CSF, and detection of this protein can confirm a suspected CSF leak. ...
